Pet owners who own multiple pets, such as dogs and cats, may worry about their pets mating with each other and giving birth to a hybrid offspring. But is it really possible? Can a dog and a cat have a baby together? Can they mate and give birth to hybrid offspring?

The simple answer to these questions is, No, they can’t. Although it may seem a far-fetched question to many, it is commonly asked by cat and dog lovers alike. So, if you are one of them and want to find an answer to the question “can a dog and a cat have a baby?” we urge you to read our detailed article to find out more. 

Why They Cannot Mate?

Can a dog and a cat have a baby together? We know the answer to this query is negative. But the next question that may pop up in your mind is why they can’t? If they live together and seem to have some physical similarities, then why can’t they mate and produce hybrid offspring?

The answer lies in the genetic makeup of dogs and cats. They cannot give birth to a hybrid because these two are entirely different from one another. They both may like to sit on your couch, be equally affectionate towards you, or like to consume meat, but they differ a lot in their biology and genetics.

Differences in the Bodies

The differences that make them incompatible to mate with one another or produce hybrid offspring are discussed in detail below. So, to better understand why a dog and cat cannot mate and give birth to hybrids, let’s first discuss the basics of the genetic makeup of a dog and cat.

Genetic Makeup and Heredity

Every organism on the surface of this earth has its own heredity and DNA material that decides the unique appearance and physical makeup of that organism. This DNA material is what we call chromosomes. When it comes to the genetic makeup of cats and dogs, it is important to mention here that a cat has 19 pairs of chromosomes, whereas a dog has 39. This difference in the number of their chromosome pairs makes them incompatible with reproducing and giving birth to young hybrids, even if they get to mate. If their DNA is genetically modified by scientific intervention, developing a hybrid offspring is impossible. The hybrid won’t be able to survive and would die quickly after being born.

Copulating Difficulties

Due to the differences in their bodies, it is not possible for a dog to mate with a cat or vice versa. The sexual organs in both these animals are different from one another and are developed specifically to copulate with their own kind. Cats and dogs cannot copulate with other each other because their bodies are designed differently. Additionally, a female dog and a cat go into heat at different times, so they are not interested in mating with each other. Also, their reproductive organs produce reproductive cells that cannot fuse together, making it impossible for them to develop an embryo.


Another important reason why cats and dogs cannot reproduce is the difference in their diets. Cats are carnivores, and meat is an essential item of their diet, whereas dogs are omnivores. They have different digestive systems, and their bodies need different types of nutrients to function. So, for a cat or dog to carry a hybrid offspring and give birth to it is out of the question.

Why Does a Dog Hump a Cat?

Now that we know the answer to the question “can a dog and a cat have a baby?” is No, we would focus on our next question—why do dogs hump a cat when they are not physically compatible to mate with them? 

It is a common concern for parents of multiple pets to keep them away from each other to avoid incompatible mating. But oftentimes, dogs can be seen mounting or humping other animals. So, why do they do that? Below, we have listed some of the possible reasons why your dog may be humping other pets.

What to Do If They Mate?

As we have already discussed above, it is physically impossible for a dog a cat to mate even if they try to. Due to huge differences in their biology and reproductive systems, it is impossible for them to copulate. But even if they somehow figured out how to mate, none of them can impregnate the other because they lack the required system to reproduce and carry a cat-dog hybrid to full term or give birth to him.

So, if you find out your cat and dog have mated, there is nothing to worry about. But you should take them to a vet’s clinic for a physical exam to rule out any harm or damage to their sexual organs and reproductive system. To be on the safe side, you can consider spaying or neutering your dog to prevent him from unwanted mating.

Final Words

So, we hope our comprehensive article helped clear the confusion regarding a common question, “Can a dog and a cat have a baby?” They cannot mate or copulate and give birth to a cat-dog hybrid, also known as a kuppy, dat, cog, ditten, or a puppy-cat.

Except for their affection towards their owners and their love to lay on a couch, there is nothing common in these pets. The male dog doesn’t find a female cat attractive and vice versa. Also, their females have different reproductive cycles, and they go into heat at separate times.

Crossing these two animals is impractical even after scientific intervention. If their DNAs are genetically modified, their bodies would still not be able to carry the hybrid offspring to full term. They would die right after being born or may even die before being born.
